Watch This Video of 400 Students Singing to A Teacher With Cancer

The latest video to go viral is music to our ears, literally: To show their support for a teacher battling cancer, an entire high school student body and faculty gathered outside his home to serenade him.

The teacher is Ben Ellis, who has been teaching Latin and Bible at Christ Presbyterian Academy in Nashville, Tennessee, since 2008. Last year, when he was diagnosed with cancer, Ellis remained involved in the school community. His own five children also attend the school.

And so, to give back to their beloved teacher, students in grades 9 through 12 and Ellis's fellow faculty members spent 30 minutes singing and playing instruments outside of his' home. "It was one of the most beautiful things I've ever seen in my entire life," Christ Presbyterian Academy headmaster Nate Morrow told ABC News. "He is one of the kindest and intentionally loving people I've ever met in my life. I think that's what really characterizes him. He's always pursuing other people in wanting to get to know them and love them."

The video of Ellis watching his students' performance from an upstairs window caught the eye of country singer Tim McGraw, who shared it on his Facebook page. Since McGraw posted it on Sept. 10, the video has received roughly 24 million views. See it for yourself, below:

No, you're crying!

Yesterday, Ellis appeared on Good Morning America and said of the experience: "In that moment, I felt like I was not alone."
